You can do the whole program in Scheme as a one-liner with no conditional at all: (define (infix x) (eval ((cdar x) (car x) (cddr x))) Where x is assumed to be a list like '(1 + 2) so that (infix '(3 * 4)) ==> 12 The ability to evaluate data as code (and vis versa) is a Good Thing. BTW, this works with any valid Scheme function with an arity of 2: (infix '(a cons b)) ==> (a b) Of course, there's no error checking in case the arguments are bogus, but there wasn't any in the other version either, so...
